Questions
How big is the Flipdot PCB?
It measures 121.3 × 197.5 mm and has 2 copper layers, 0.8 mm thick.
What parts does the Flipdot use?
521 parts, built around the 74HC595, FDN338P and NSMD050-33V. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Flipdot KiCad files?
From the mitxela/flipdots repository on GitHub, at the commit this page was made from: the board is drivers-full/flipdot.kicad_pcb and its schematic decode/flipdot-decode.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Flipdot design in my own project?
Its repository states no licence, so its author keeps all rights: ask mitxela before reusing the design.
